NIPPERS.

SPECIFICATION forming part of Letters Patent No. 419,666, dated January 21, 1890. Application filed April 27, 1881- Serial No. 31,902. (ModeL) Patented in France February 20, 1880,1Toi185,1'76.

To all whom it may concern:

Be it known that I, THOMAS G. HALL, of Milford, county of New Haven, and State of Connecticut, have invented certain Improvements in Cutting-Nippers, (and for which I obtained a patent in France dated February 20, 1880, and numbered 135,176,) of which the following description, in connection with the accompanying drawings, is a specification.

This invention consists of certain improvements upon the cutting-nippers for which Letters Patent of the United States were granted to me May 14, 1867, No. 61,664, and also November 5, 1878, No. 209,677.

Figure 1 is an external, and Fig. 2 an internal, view of said cutting-nippers with my improvements thereto applied.

My improved nippers consist of a pair of jaw-levers 0 cl, upon the outer ends of which cutting-edges 0 cl are formed, and upon the inner ends of which bearings are formed to match upon the inner ends 9' h of a pair of handle-levers g it. These jaw-levers and the inner ends of the handle-levers are inclosed between a pair of side plates a,

seen, are fitted between the long ends of the jaw-levers, and the cutting ends are kept from slamming together by the adjustable pin a, adjusted to strike the handle-lever h, so as to save the cutting-edges from actual contact. Now, to separate the cutting-edges after they have been forced together by the handles, a spring f is inserted between them, in the manner shown in the drawings, the two limbs of this spring being set into a seat cut into the inside edges of each jaw-lever, said seat having a lip or projection e I) over its upper end to keep the spring from riding up out of its place. To cause the two handle-levers and the cutting-edges to move in unison, the two handle-levers are connected, as at m, opposite the fulcra 4 5, by a prong and notch conneotion,or, by what is the same thing, a section of cog-gearing.

Having thus described my improvement, I claim and desire to secure by Letters Patent- The body composed of the side plates, the independent fnlcra for the jaw-levers and handle-levers, the jaw-levers provided with cutting-edges and with lips, and the handlelevers, having short arms and a prong and notch always in engagement, combined with the V-shaped spring held by the lips and the jaw-levers. I

In testimony whereof I have signed my name hereto in the presence of two subscribing witnesses.

THOMAS G. HALL.
